Abstract: Abstract: In this article the seeds of Red fescue (Featua fubra L.), a cold-season type turf grass, were soaked with five kinds concentration of salicylic acid (SA) as 0.25, 0.5, 1.0, 2.0, 4.0 mmol/L. Under cold stress of 4 ℃ for 48 hours, the proline content, the Malondialdehyde (MDA) content and the electrolyte leakage in the Red fescue were determined. The result showed that the suitable concentration salicylic acid could increase the proline content, decrease the content of MDA which was a product of membrane lipid peroxidation, and reduce the electrolyte leakage rate in the Red fescue, which could improve the cold resistance ability of the Red fescues.
